Subject Re: Classloading Error with Kotlin and Streams

Hi Avi,

I've done a little digging. Unfortunately, I don't have any answers at this

Here's what I did:

   1.  I replicated your CLI command in a standalone class
   (TestDeserializerLoader.kt in IntelliJ) and created an uber-jar file.  I
   can reproduce your error with "kotlin -cp <path-to-jar>
   2. If I execute the same command with java, everything works (no big
   surprise there!)
   3. To see what classes the programs load,  I added the
   -J-verbose:class/-verbose:class flag to the kotlin/java processes
   respectively and captured the results in a file.
   4. I grepped for 'serialization, ' and in both files, there is the
   following line [Loaded
   org.apache.kafka.common.serialization.Serdes$ByteArraySerde from

I've attached the serialization classes loaded from both commands.

For us to go further, I think you'll need to put a JIRA ticket in, sorry
this isn't very helpful at this point.
